Specification of Letters Patent.

Application `i1ed March 23, 1910. Serial No. 551,137.

To all whom it may concern:

Be it known that I, JAMES A. RODMAN, a citizen of the United States,residing at llVynne, in the county of Cross and State of Arkansas, haveinvented certain new and useful Improvements in Plows, of which thefollowing is a specification.

My device has relation to new and useful improvements in plows andespecially to the colters thereof.

The main object of my invention is to produce means whereby the coltermay be adjusted vertically or the angle that it forms with a verticalline may be varied.

Another object of my invention is to produce the above results and, atthe same time, have a plow that will be streng, durable and eliieient.

I preserve the strength of the beam by a particular method which will befully pointed out in the following specification.

lVith the above and other objects in view my invention consists in thenovel construction and arrangement of parts as are described in thisspecification, illustrated in the accompanying drawings forming a partthereof and pointed out in the appended claim.

Having reference to the drawings: Figure l is a side elevation of thedevice. Fig. 2 is a top plan view thereof, partly broken away, thecolter being not shown. Fig. 3 is a perspective view of that part of thebeam upon which the collar is mounted that supports the colter. F ig. 4fis a detail.

My invention is described as follows: The beam l of the plow is providedwith a longitudinally disposed vertical slot 2, passing therethrough. Ablock 3 is interposed between the inner walls of said slot about mid waythe ends of said beam. The longitudinal slot is just suliiciently wideto accommodate the thickness of the colter 4, thus the strength of thebeam is preserved which is very necessary to the durability of the plow.Encircling said beam near the rear end thereof is a collar 5, whichcollar is provided with lugs 6 and 7 and a slot 8 which registers withthe slot 2. A perforation 9 is provided in the under face of the lcollar through which the reduced portion l0 of said colter passes. Saidreduced portion also passes through said slot 8. Thus it will be seenthat while that part of the reduced portion l0 which passes through theperforation 9 is held against forward or rearward movement and that partwhich passes through the slot is adapted to be adjusted forward orrearward by means of a set screw 1l, the angularity of the plow inrelation to a vertical line may be altered. I Said set screw ll passesthrough a threaded perforation l2 in said lug 7.

The position of the collar 5 upon the beam l may be altered when desiredand may be held temporarily in any position by means of the grass rods14, which rods engage the collar by means of the perforated lug 6 andthe perforation l5, which perforation is in the under side of saidcollar. As

shown, the collar is held against backward movement upon the beam bymeans of the shoulders l1 of said beam. The collar 5 is provided withset screws 13 in one of its side walls, which screws close the slot,pressing its inner walls against the colter 4c and thus preventingvertical movement thereof, l A metallic strip 16 having a slot throughwhich passes said colter 4 runs along the lower face of said beam andadds strength thereto.

Although I have specifically described the construction of my plow yet Imay reserve I and exercise the right to make such changes l therein asdo not depart from the spirit of my invention or the scope of theappended claim.

I-Iaving described my invention what I claim as new, is:

A plow whose beam is provided with a longitudinal vertically disposedslot, a collar encircling the beam and provided with a slot in its upperportion registering with said first-mentioned slot and further providedin its under side with a perforation, l a perforated lug formed integralwith the l rear upper edge of the collar and a perfora* tion in theunder side of the collar, grass rods interposed between the collar andthe standard, one of the rods connected to said lug, the other connectedto the collar by collar upon the beam against forward or means of innerwalls of the perforation, a rearward movement. 10 colter the reducedportion of which is In testimony whereof I afx my signaadapted to passthrough the said perforature, in presence of two witnesses.
